Abstract
A reversible direct current, winch motor is controlled by a 'dead man' switch. The switch includes a handle pivotally attached to a plug and normally maintained in a neutral position relative to the plug. The plug is received in a receptacle defined in the winch housing. Leads in the receptacle from the motor are normally shunted to provide a winch braking effect. Directional pivotal movement of the switch handle causes power leads in the handle to pivot and engage the motor leads and thereby provide subsequent directional operational of the motor. The handle and plug, as well as the power input leads, are removable from the receptacle for safety and security purposes.
